Benefits of technology

[0008]The present invention enables real time image development processing that accompanies movie playback to be performed with a small circuit scale and low power consumption using simple image development with a small amount of processing, and also enables high quality images to be provided under predetermined conditions.

Problems solved by technology

As a result, large circuitry and much power consumption may be required when performing image development processing concurrently with image shooting.
In some cases, it may not be possible to realize high image shooting performance because of limitations on the space occupied by circuits or the power consumption needed for image development processing, for example.

first embodiment

[0023]FIG. 1 is a block diagram that shows an exemplary configuration of an image capturing apparatus according to a first embodiment of the invention. The image capturing apparatus 100 shown in FIG. 1 has functions of capturing an image of an object and recording the obtained image information to a recording medium, and additionally has functions of playing back the image information from the recording medium, and performing image development processing on the image information and displaying the image information, and also has functions of sending / receiving the image information to / from an external device or server (cloud), or the like. Accordingly, the image capturing apparatus according to an embodiment of the invention can represent, for example, an image processing apparatus, a recording apparatus, a playback apparatus, a recording / playback apparatus, or a communications apparatus.

[0024]As the image capturing apparatus 100, it is possible to adopt, other than a digital camera,...

second embodiment

[0084]In the case described in the first embodiment, from a normal playback state in which image development processing of RAW image data at 60 frames per second is necessary, by altering the display rate of frame images, the image processing apparatus changes to a state used during a temporary stoppage, in which it is permitted to develop a single image. In this state, image development processing performed on RAW image data is switched from simple image development processing to high quality image development processing. However, changing of the display rate is not limited to being performed during a temporary stoppage, and may also be performed when reducing playback speed, i.e., during slow playback.

[0085]Consequently, in the case described in this second embodiment, an instruction for slow playback has been given during movie playback. The configuration of the image capturing apparatus according to the present embodiment is similar to the configuration described in the first em...

Abstract

An image processing apparatus comprising a reading unit reading out a movie file including RAW image data from a recording medium, an image development unit developing the RAW image data, a display control unit controlling a display unit to display the RAW image data that were developed, and an operation unit instructing a display rate of an image displayable by the display unit, wherein the image development unit executes image development by switching between first image development processing and second image development processing, the image development unit switches image development processing of the RAW image data from the first image development processing to the second image development processing in response to an instruction to lower the display rate while the RAW image data developed by the first image development processing is being displayed.

Description

BACKGROUND OF THE INVENTION[0001]Field of the Invention[0002]The present invention relates to an image processing apparatus, a method for controlling the image processing apparatus, and a non-transitory computer readable storage medium.[0003]Description of the Related Art[0004]An image capturing apparatus converts undeveloped image information (a RAW image) captured by an image sensor into signals including luminance and color differences. So-called image development processing, for example, such as noise reduction, optical distortion correction, or image optimization, is performed on each of the obtained signals. After the image development processing has been performed on these luminance and color difference signals, the signals undergo compression encoding, and then the compressed signals are recorded to a recording medium.[0005]On the other hand, an image capturing apparatus that can record a RAW image itself also exists. Although a large amount of data is needed for recording a...
